3 Claims.

This invention relates to a hinge.

An important object of this invention is to provide a hinge of novel construction suitably made of sheet metal by easy stamping and forming operations, and characterized by light weight and convenient assemblage.

A specific object of this invention is to provide a rising hinge having the above noted characteristics.

Other and further objects and features of this invention will be apparent from the following description and appended claims as illustrated by the accompanying drawings which show, by Way of examples, hinges constructed according to the present invention. More specifically:

Figure l is a bottom plan view of a hinge according to the present invention in open position;

Figure 2 is a section along the line 2-2 of Figure 3;

Figure 3 is a side elevation of the hinge of Figures 1 and 2;

Figure 4 is an exploded perspective view of the hinge of Figures 1 to 3;

Figure 5 is a bottom plan view of a rising hinge according to the present invention in open position;

Figure 6 is an elevation of the hinge of Figure 5;

Figure 7 is another elevation of the hinge of Figure 5 viewed from the opposite side;

Figure 8 is a section taken along the line 8- 8 of Figure 6;

Figure 9 is an exploded perspective view of the hinge of Figures 5 to 8;

Figure 10 is a fragmentary side view of a modifled leaf of a hinge otherwise similar to that of Figures 5 to 9;

Figure 11 is a fragmentary edge view of the modified leaf of Figure 10; and

Figure 12 is a fragmentary edge view of a modification of one leaf of the hinge of Figures 5 to 9.

Referring now to Figures 1 to 4, there is shown a hinge comprising a first generally rectangular leaf l0 and a second also generally rectangular leaf l 2, each adapted to be attached to one of two members to be hingedly connected. The leaf H3 is provided with two spaced aligned tubular ears I l and It both attached to one side of said leaf It. Further, a web I8 spans part of the interspace between the two ears i4 and I6, leaving a longitudinal slot between the web I8 and that side of the leaf iii to which the ears [4 and iii are attached. The web I8 is curved similarly to the cars It and I6 and forms a partial continuation thereof. Preferably, the leaf H), the ears l4 and l6 and the web I8 are formed integrally from a single piece of sheet metal stamped to provide a longitudinal slot corresponding to the slot 26, and two transversely projecting tongues. The margin of the sheet metal piece including said longitudinal slot and said transverse tongues is then bent back upon itself tubularly to form the finished leaf It with its ears [4 and i6 and web H3.

The leaf i2 is provided with a knuckle 22 pro jecting from one side thereof and adapted to be inserted between the ears Hi and iii of the leaf It in general alignment with said ears. The terminal portion 24 of the knuckle 22 is considerably thicker than the remaining proximal portion of the knuckle. The leaf i2 and knuckle 22, 24 are also suitably made integrally from a single piece of sheet metal stamped to provide a transverse projecting tongue corresponding to the knuckle 22, 2d. The terminal portion of this tongue is folded back upon itself, preferably tubularly, to provide the thick distal knuckle portion 24.

The hinge of Figures 1 to 4 also comprises a tubular pivot pin 26 formed with a longitudinal slot 28 of a width smaller than the thickness of r the terminal knuckle portion 2% of the leaf 12.

The pin 26 may also be formed, at one end with a radial flange 30 adapted to abut the terminal edge of one of the ears M, It of the leaf Ill.

The pivot pin 26 fits slidingly within the ears l4 and 16, while the knuckle portion 24 fits slidingly within the pivot pin 26.

The above mentioned parts are assembled by inserting the knuckle portion 2d through the slot 2e into generally concentric and aligned relationship with the ears [4 and I6. Next, the pivot pin 25 is threaded (unflanged end first) into the two ears I4 and I6, being then passed around the thick terminal portion 2 3 of the knuckle 22.

When the hinge of Figures 1 to 4 has been assembled, the leaves ill and I? are freely movable with respect to one another over an angle determined by the angular extent of the slot 29. For instance, the web l8 may extend around 270 of the tubular ears l4 and i6, and then the two leaves may be moved from abutting relationship into the 90 angular relationship shown in Figures 1 to 3.

In the hinge of Figures 1 to 4 the pivot pin 26 moves with the leaf [2, since the pivot pin slot 28 abuts the opposed sides or faces of the knuckle 22 of the leaf l2. The flange 30 of the pivot pin 26 rests upon the top edge of the ear i4 and thereby holds the pivot pin in assembled position.

For disassembling the hinge of Figures 1 to 4, it is only necessary to pull out the pivot pin 2t.

The knuckle 22, 24 may then be pulled out through the slot 20 to separate the leaf l2 from the leaf Ill.

The hinge of Figures to 9 is constructed of parts similar to the hinge of Figures 1 to 4 and the same reference numerals are therefore used, the letter a being added for the numerals of Figurs 5 to 9. The hinge of Figures 5 to 9 functions essentially similarly to that of Figures 1 to 4 except for the features discussed hereinbelow.

In the hinge of Figures 5 to 9, the ears 14a and lBa have their opposed edges extending along parallel spiral lines. The slots indicated at 29c provide for entrance of the knuckle portions 2% between the ears Ma and to. These slots 28a are defined by the opposed surfaces-of the-spaced ears Ida and [6a. The web portion 18a located between said pair of ears Ma and 16a defines the angular extent of slot 28a and serves :to limit the range of swinging of the leaves Ilia and 120: with respect to each other. Further, the relatively thick terminal knuckle portions 24a are restricted lengthwise with respect to the proximal relatively thin knuckle portion 22a. The upper and lower edges of the proximal knuckle portion 22a slide over the spiral edges of the ears Ma and ita as the hinge is opened and closed. As a consequence, the leaf E20, rises and falls as the hinge is opened and closed. The hinge of Figures 5 to 9 is therefore a hinge of the type known as a rising hinge. The reason for the restriction of the terminal knuckle portion 24a is the fact that in the absence of such a restriction the terminal knuckle portion 24a could not pass through the slots defined by the opposed surfaces of the ears Ida and lSa due to the thickness of this knuckle portion. In other words, the upper and lower transversely opposed corners of the terminal knuckle portion 24a could not clear the opposed spiral edges of the ears Ma and 16a.

As shown in Figure 12, the upper and lower surfaces of the knuckle portions 22a may be sloped similarly to the opposed surfaces of the ears Ma and Mia to provide extended surface contact therewith.

Instead of restricting the terminal portions 24a in the manner shown in Figures 5 to 9 (by having one or both ends of the terminal knuckle portion 24a extending short of the proximal knuckle portion 22a) to permit assemblage of the hinge, the

same end may be reached by the structure shown in Figures and 11, which illustrate another rising hinge constructed according to the principles embodied in the hinge of Figures 5 to 9.

As shown in Figures 10 and 11, a leaf [2!) is formed with a knuckle 221) having a terminal relatively thick portion 26b. The upper and lower surfaces 240 of the terminal knuckle portion 241) slope downwardly in parallelism. The slope of these surfaces Z lc conforms with the slope of the parallel edges of the ears Ida and liia to permit insertion therebetween of the knuckle portion 24b.

The hinge of Figures 5 to 9 may be fabricated from sheet metal similarly to the hinge of Figures 1 to 4.

The hinges shown by way of examples in the drawings are formed with specific numbers of cars and knuckles. It will be understood that other numbers of ears and knuckles may be provided. Further, the ears Ma and lSa may have opposed edges of other curvature than the spiral form shown in the drawings.

Many other details of construction may be varied without departing from the principles of this invention, and it is therefore not my purpose to limit the patent granted on this invention otherwise than necessitated by the scope of the appended claims.
